To spread bet, you open an account with a provider regulated by the UK’s Financial Conduct Authority, pass an identity check and an appropriateness assessment, fund the account, then choose a market, pick a direction, set your stake per point, attach a stop loss, and submit the order on the provider’s deal ticket. You never own the underlying asset. You’re betting on price movement with leverage, so a small deposit controls a much larger position, and profits for UK residents are currently free of capital gains tax.
The rest of this guide walks through each step and the rules that shape it.
Who Can Spread Bet
Spread betting as a regulated financial product is offered mainly in the United Kingdom and Ireland. The FCA oversees UK providers under its Conduct of Business Sourcebook, which imposes leverage caps, requires risk disclosures, and mandates appropriateness checks before a provider can let you trade.
US residents cannot legally open spread betting accounts. Spread bets function as over-the-counter derivatives, which puts retail participants outside what the Commodity Exchange Act permits. No major UK firm accepts US clients, and using a foreign address to get around that creates serious legal exposure. If you’re in the US and want leveraged exposure, contracts for difference on a registered exchange or exchange-traded options are the regulated alternatives.
Opening an Account
Identity Verification
Every FCA-regulated provider has to verify who you are before activating your account. You’ll give your full name, residential address, date of birth, and a government-issued photo ID such as a passport or driving licence. Most platforms also ask for proof of address, typically a recent utility bill or bank statement. Almost all of this is done digitally now, and automated document scanning can clear you within minutes.
The Appropriateness Assessment
Before you can place a trade, the provider has to assess whether spread betting is appropriate for you. This isn’t a formality you can click through. You’ll be asked about your experience with leveraged products, your understanding of how losses can exceed deposits, and your familiarity with margin and short selling.1Financial Ombudsman Service. Spread Betting and Contracts for Difference You’ll also answer questions about income, net worth, and employment so the provider can judge whether you can absorb losses.
If the assessment concludes spread betting isn’t appropriate for you, the provider must warn you. Some will still let you proceed after you acknowledge the warning; others restrict the account. Answering dishonestly to skip past the check defeats its purpose and leaves you exposed to risks you may not actually understand. Providers also have to display the percentage of their retail accounts that lose money, and that figure typically sits between 65% and 80%.
The Costs Built Into Every Trade
The Spread
Spread betting providers don’t charge commissions on most trades. They build their profit into the spread, which is the gap between the buy price and the sell price. If the FTSE 100 is trading at 7500 in the underlying market, your provider might quote 7499 to sell and 7501 to buy. Your trade starts slightly in the red by that two-point difference, and the market has to move past it in your favor before you break even.
Spread widths vary. Major forex pairs like GBP/USD often carry spreads of one or two points, while small-cap shares or exotic currencies can be far wider. Spreads also widen during volatility or low liquidity, such as around a major economic announcement or overnight when the underlying exchange is closed. Checking the typical spread for your market before trading is one of the easiest cost controls you have.
Overnight Financing
Hold a bet past the end of the trading day and the provider charges a daily financing cost. Your leveraged position is effectively a loan: you’ve deposited a fraction of the total position value, and the provider is financing the rest. The charge is calculated by reference to an interbank interest rate plus a markup, applied to the full notional value and divided by 365. On a long position you pay this every night. On a short position you may receive a small credit if the interest rate exceeds the markup, though in practice that credit is often negligible or zero.
Over weeks or months, these charges erode profit. A trade that looks profitable on price alone can turn into a loss once cumulative financing is counted. Spread betting fits short-term trading more naturally than buy-and-hold for exactly this reason. If you do plan to hold for longer, compare financing rates between providers, because the markup above the benchmark rate varies.
Leverage and Margin
Leverage is the defining feature of spread betting and the source of both its appeal and its danger. You don’t deposit the full notional value of the position. You put up a margin deposit, typically between 3.3% and 20% of total exposure depending on the asset. A 5% margin requirement means £1,000 controls a £20,000 position, giving you 20:1 leverage.
The FCA caps leverage for retail clients by market:
- Major currency pairs: 30:1 (3.3% margin)
- Major stock indices and gold: 20:1 (5% margin)
- Other commodities and minor indices: 10:1 (10% margin)
- Individual shares: 5:1 (20% margin)
- Cryptocurrencies: 2:1 (50% margin)
Leverage magnifies losses at the same rate it magnifies gains. At 20:1 leverage, a 5% move against you wipes out your entire margin. Before these caps, retail clients could access 200:1 or higher, and catastrophic losses were common.
Margin Calls and Negative Balance Protection
If your positions move against you and your account equity drops, you’ll face a margin call asking you to deposit more. Under FCA rules, if your account equity falls to 50% of the total margin required to maintain your open positions, the provider must begin closing your trades.2Financial Conduct Authority. COBS 22.5 Restrictions on the Retail Marketing, Distribution and Sale of Speculative Investments That forced liquidation is automatic and often happens at the worst possible moment, locking in losses that might have recovered with more margin to absorb the drawdown.
Providers also have to offer negative balance protection to retail clients. Your losses cannot exceed the funds in your trading account. If a sudden market gap pushes your position to close at a price worse than your stop loss and the balance goes negative, the provider has to absorb that loss rather than pursue you for the difference.2Financial Conduct Authority.

Setting Up the Trade
Market and Direction
Pick a market first. Providers typically offer thousands of instruments across forex, stock indices, individual shares, commodities, bonds, and sometimes cryptocurrencies. Each has its own margin requirement, spread, and trading hours. If you’re starting out, highly liquid markets like major forex pairs or the FTSE 100 give you tighter spreads and more predictable behavior.
Then decide direction. Going long means you profit if the price rises. Going short means you profit if it falls. That flexibility is one of spread betting’s strengths over conventional share dealing, where profiting from a decline requires more complex arrangements. You select direction on the deal ticket, which is the order-entry screen your platform shows when you click on a market.
Sizing Your Stake
Your stake is the amount you win or lose per point of price movement, and it’s the single most important number in the bet. A £5-per-point stake on the FTSE 100 that moves 30 points in your favor makes £150; the same move against you loses £150. The stake also drives your total exposure: £10 per point on a market trading at 7500 creates £75,000 of notional exposure, and that’s the figure used to calculate margin.
New traders consistently set the stake too high. A better approach is to work backward from the amount you’re willing to lose on the trade. If you have a £5,000 account and don’t want to risk more than 1% on any single trade, your maximum loss is £50. If your stop loss sits 25 points away, your stake should be £2 per point. Running that arithmetic before you touch the deal ticket prevents the outsized loss that ends an account early.
Stop Loss and Take Profit
A stop loss is an instruction to close your bet automatically if the price reaches a level where you want to cut losses. You enter it as a specific price on the deal ticket. Without one, your position stays open and losses keep growing until you close it manually, your margin runs out and the provider forces closure, or the market reverses. Using a stop loss on every trade is the closest thing to a universal rule in leveraged trading.
A standard stop loss isn’t guaranteed to execute at the exact price you set. If the market gaps through your level overnight or in a sharp move, you’ll close at a worse price. Most providers offer a guaranteed stop loss as an alternative, which executes at exactly the price you specify regardless of gaps. The catch is a premium, charged either as a wider spread or as a separate fee if the stop is triggered. For positions held over events that could cause sharp moves, that premium is usually worth paying.
A take profit order works in reverse. It closes your bet when the price hits a target where you want to lock in gains. Setting both a stop and a target before you place the trade forces you to define risk and reward in advance, which is far more disciplined than reacting to the screen in real time.
Placing, Watching, and Closing the Trade
Once you’ve set the market, direction, stake, and protective orders on the deal ticket, you submit by clicking the execution button. The platform fills the order at the current quoted price and shows a confirmation with the execution price, timestamp, and order details. That confirmation is your transaction record.
The trade then appears in your open positions, where you can watch real-time profit or loss as the market moves. Most platforms also show margin usage, available equity, and the distance to your stop and target levels. Watching a leveraged position tick by tick is psychologically intense, especially early on. If your stop and target are set correctly, there’s rarely a good reason to stare at the screen. The orders exist so you don’t have to.
You can close at any time during market hours by going to open positions and clicking close. The platform executes an offsetting trade at the current price, and your profit or loss is the difference between opening and closing price, multiplied by your stake. A £3-per-point bet that opens at 7500 and closes at 7520 makes £60. The same bet closing at 7480 loses £60. Your balance updates instantly and the position moves to trade history. If your stop or target triggers first, the bet closes automatically and you don’t need to be logged in. Some forward-dated bets on futures markets also close automatically on a fixed expiry date, but most rolling daily bets have no expiry and stay open until you close them or get stopped out.
Tax on Spread Betting for UK Residents
Spread betting profits are currently free of capital gains tax in the UK. HMRC classifies spread betting as gambling rather than as trading in financial instruments, so no chargeable gains or allowable losses arise. You don’t report the profits on your tax return, and you don’t pay stamp duty because you never own the underlying asset.
The flip side matters. Because losses are gambling losses in HMRC’s eyes, they can’t be offset against other taxable gains. Lose £10,000 spread betting and make £10,000 on share dealing in the same tax year, and you still owe capital gains tax on the full share dealing profit. The tax-free status is valuable when you’re profitable and offers nothing when you’re not. That’s worth weighing before you treat the tax treatment as a reason to prefer spread betting over other forms of trading.
